Actually a chaos dwarf warrior is a fairly stout deal. Both in point cost and stats, blunderbuss is costly, fireglaves is where the love is at. Magma cannons are going to make everyone cry, doom rockets are now just evil and the doom siege mortar is just wrong on so many levels. The only entry that's not truly worth there cost are the fell-sworn iron guard. For a special choice there cost are really high, there stats good but no special rule that truly makes them worth there very high cost.
